K. Frikach et al., VORTEX LATTICE IN THE SUPERCONDUCTOR-CONDUCTOR TRANSITION REGION AND THE VOLTAGE NOISE IN A HIGHLY TEXTURED THIN-FILM OF YBA2CU3O7-DELTA, Physica. C, Superconductivity, 282, 1997, pp. 1977-1978
Voltage noise is measured in thin film of YBa2Cu3O7-delta submitted to
a field parallel to the c axis in the transition region. The noise pr
esent a sharp peak which occurs above a well defined temperature Tcd T
his peak depends strongly on the applied field. The interpretation of
the peak is based on the motion of a correlated flux bundles.
